Eravacycline (TP-434) is active in vitro against biofilms formed by uropathogenic Escherichia coli.
    Antimicrobial agents and chemotherapy, 2015, Volume: 59, Issue:4

    Eravacycline (formerly TP-434) was evaluated in vitro against pre-established biofilms formed by a uropathogenic Escherichia coli strain. Biofilms were eradicated by 0.5 μg/ml eravacycline, which was within 2-fold of the MIC for planktonic cells. In contrast, colistin and meropenem disrupted biofilms at 32 and 2 μg/ml, respectively, concentrations well above their respective MICs of 0.5 and 0.03 μg/ml. Gentamicin and levofloxacin eradicated biofilms at concentrations within 2-fold of their MICs.

Activity of Eravacycline against Escherichia coli Clinical Isolates Collected from U.S. Veterans in 2011 in Relation to Coresistance Phenotype and Sequence Type 131 Genotype.
    Antimicrobial agents and chemotherapy, 2015, Dec-14, Volume: 60, Issue:3

    Eravacycline is a novel broad-spectrum fluorocycline with potent Gram-negative activity, including for multidrug-resistant strains. Among 472 Escherichia coli clinical isolates from 24 Veterans Affairs medical centers (in 2011), divided equally as susceptible versus resistant to fluoroquinolones, broth microdilution eravacycline MICs were distributed unimodally, ranging from 0.03 to 1.0 μg/ml (MIC50 of 0.125 μg/ml, MIC90 of 0.25 μg/ml). Eravacycline MICs were ∼ 2-fold higher among fluoroquinolone-resistant, gentamicin-resistant, multidrug-resistant, and sequence type 131 (ST131) isolates (P < 0.01 for each comparison).

Fluorocyclines. 1. 7-fluoro-9-pyrrolidinoacetamido-6-demethyl-6-deoxytetracycline: a potent, broad spectrum antibacterial agent.
    Journal of medicinal chemistry, 2012, Jan-26, Volume: 55, Issue:2

    This and the accompanying report (DOI: 10.1021/jm201467r ) describe the design, synthesis, and evaluation of a new generation of tetracycline antibacterial agents, 7-fluoro-9-substituted-6-demethyl-6-deoxytetracyclines ("fluorocyclines"), accessible through a recently developed total synthesis approach. These fluorocyclines possess potent antibacterial activities against multidrug resistant (MDR) Gram-positive and Gram-negative pathogens. One of the fluorocyclines, 7-fluoro-9-pyrrolidinoacetamido-6-demethyl-6-deoxytetracycline (17j, also known as TP-434, 50th Interscience Conference on Antimicrobial Agents and Chemotherapy Conference , Boston, MA , September 12-15, 2010 , poster F1 - 2157 ), is currently undergoing phase 2 clinical trials in patients with complicated intra-abdominal infections (cIAI).
